Sharper Filter Edge

The high performance model can also achieve a higher dynamic range within 0.2nm of the peak wavelength. With the sharper spectral characteristics of the monochromator, spectral signals in close proximity can be separated clearly and measured accurately.

Example of the spectral shape

Stray-light suppression ratio: 80dB typ.

This new specification provides stray-light suppression capability when High dynamic mode, usually taking longer measurement time, is not used. The AQ6370C contributes to shortening the measurement time with the high stray light suppression ratio.

Wide Level Range: +20DBm to -90dBm

The AQ6370C can measure high power sources such as optical amplifiers and pump lasers for Raman amplifiers, and very weak optical signals as well. Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements.

Improved level sensitivity: -85dBm (1000 to 1300nm)

Smoothing Function - Reduce noise on the measured spectrum

High dynamic mode - Obtain a better dynamic range by reducing the influence of stray-light, which is caused when the input is a strong optical signal.

Free Space Input

Multimode and single mode fiber on the same OSA.

AQ6370C's low insertion loss for multimode fiber is also beneficial to maintain the excellent measurement efficiency.

Excellent Efficiency

Fast Sweep: 0.2sec./100nm

With an advanced monochromator, faster electrical circuits, and noise reduction techniques, the AQ6370C achieves fast measurement speed even when measuring a steep spectrum from DFB-LD or DWDM signals, or when measuring a low power signal from a broadband light source.

Mouse & Keyboard Operation

Front panel operation proven intuitive and easy to use by our many of users.

Easy to Keep Accurate

Ambient condition change, vibration and shock to an optical precision product, like an optical spectrum analyzer, will effect the optical components, and eventually degrade optical performance. Using standard functions, AQ6370C can maintain its high optical performance within a couple of minutes so that you can quickly start a measurement.

Built-in wavelength reference source

AQ6370C comes equipped with a wavelength reference source for the wavelength calibration and optical alignment.

Wavelength calibration function

Automatically calibrates with the built-in wavelength reference or an external light source, to ensure the wavelength accuracy.

Optical alignment function

Automatically aligns the optical path in the monochromator using the built-in source to maintain high performance.

AQ6370C's overall high performance can cover not only manufacturing of optical devices and optical transmission systems but also research and development, and a variety of other applications.

Optical Amplifier (EDFA) Measurement

The ASE interpolation method is used to measure gain, NF, and key parameters for optical fiber amplifier evaluation. With WDM-NF analysis function, up to 1024 channels of multiplexed signals can simultaneously be tested. An ASE level for NF measurements is calculated by using a curve-fit function for each WDM channel.
